Wordle is, in its creator's own words, "a toy for generating 'word clouds.'" With this free, browser-based app, users input text or link to an RSS feed to generate word clouds - visual representations of the most commonly used words in the source text. Users are then able to tweak and customize these word clouds using a simple toolset, and save their creations to the Wordle public database.
Here are some examples of Word clouds that compare the language used by various liberal and conservative news outlets.
|The National Review|
|The New York Times|
|The Raw Story|
|World News Daily|
|The Washington Post|
|The National Journal|
Once you make a word cloud with Wordle, you have free reign to do with it as you please. Yes, that also means you can sell them.
